If humans can settle on Mars in the future, what do they need to do?

Mars is the object of interstellar migration that human beings have been longing for. Many sci-fi movies also aim at Mars to describe the story of human interstellar migration, which shows how much attention Mars has received. It is not unreasonable for people to value Mars so much, because at least there is no planet in the solar system that is more suitable for human habitation than Mars!

However, it is only relative that Mars is more suitable for human habitation. Compared with other planets and the earth, the environment of Mars is simply terrible. Even the worst environment on earth is many times better than Mars, because we have at least oxygen to breathe on earth!

The average temperature on Mars is low and the temperature difference is great. The highest temperature in the equatorial region can reach 20 degrees Celsius. However, without the protection of the atmosphere, the temperature difference is very large, and it will quickly cool down to tens of degrees below zero at night, so it is necessary to heat Mars in the future.

Fortunately, we are very experienced in warming up. In fact, our current global warming effect is our contribution to warming. Although warming is not good for the earth, we can warm Mars in this way, that is, make greenhouse gases. Humans are good at this!

It takes a long time for Mars to heat up, not overnight, but at least hundreds of years!

After Mars heats up, we try to plant some cold-tolerant and drought-tolerant plants on Mars. Plants can produce oxygen!

Of course, it is not a simple matter to make Mars warm, because the Martian environment is very bad, and it will suffer various tests in the early stage of settling on Mars, such as crazy dusty weather, violent cosmic rays, the progress of meteorites, the lack of water resources, food supply and so on!

It is foreseeable that in the early days of settling on Mars, human beings will definitely not be self-sufficient and need to provide various resources from the earth, which requires us to make a breakthrough in speed, otherwise it will definitely take at least one year to go back and forth like this!

In the early days of settling on Mars, it is still necessary to build a closed building, and the ecosystem is also closed, similar to the "Biosphere 2" made by the United States to simulate the living environment in outer space!

The most important thing is to find a truly pioneering person to explore Mars, because it is foreseeable that it will be very difficult to settle down in the early days of Mars. Without strong pressure resistance, it is the ability to adapt to unfamiliar environments, and it is absolutely impossible to complete the task of exploring Mars!
